Explanation:
B. desmosomes
C. peroxisomes
D. extracellular matrix
E. gap junctions
Answer:
E
Explanation:
Gap junctions in animals, like plasmodesmata in plants, connect the cytoplasm of two cells through dedicated and regulated channels. A gap junction is made of two hemichannels connected together leaving a channel that is 2-4 nm across -tranversing the two cells' cell membranes. The gap junctions allow for the cells to signal each other through allowing exchange of ions and other moelcules. One significance of gap junction is in enhancing communication between cells in the development of tissues and embryo.
Plasmodesmata in plant cells are most similar in function to gap junctions in animal cells.
Plasmodesmata are channels that connect plant cells and allow for the exchange of various materials, including nutrients and signaling molecules. They are most similar in function to gap junctions in animal cells. Gap junctions are specialized channels that connect neighboring animal cells, allowing for the direct transfer of small molecules and ions.
Like plasmodesmata, gap junctions play a crucial role in cell-cell communication and coordination within tissues. They facilitate the rapid passage of substances, such as ions and small metabolites, between adjacent cells, allowing for coordinated responses and sharing of resources.
Therefore, the answer to this question is E. gap junctions.

Answer:
Global climate models usually work by managing the planet as a set of connected boxes because this facilitates the management of the calculations applied in a climate system that is dynamic, variable and complex, which is due to the fact that there is not an equal pattern of climate in each area of the planet.
Explanation:
Climate models have been designed to show the dynamics of the planet's climate and what can be expected from the changes that occur in the future.
The scientific basis of a climate model is physical phenomena and chemical reactions to which a series of differential calculations are applied to determine the behaviour of:
Global climate models usually divide the planet into sections -such as boxes- making the calculations in each sector, as well as the interaction of each section with the adjacent sections, which greatly facilitates making the differential calculations, showing the climate at a given time and making predictions of future climate behavior.
It is important to mention that a climate model also explains the changes that occur in the climate due to human activity, which is different in each region of the world.

Explanation:
Plants in forest are not supplied with fertilizer by human beings ,yet they get mineral and salt from the dead decaying body of plants and animal found in the forest .Animal die in forest get converted into humus by bacteria and other animals .Sources of energy is transferred from one life to other by different means in this way plants in forest get plant and mineral.
Answer:
The major role of bacteria in the ecosystem is the decomposition of organic matters.
Explanation:
The breakdown of these organisms and the release of the nutrients back to the environment is what called decomposition. These bacteria found in our ecosystem convert gaseous substances like nitrogen into nitrates or nitrites as a part of their metabolism and the product resulting from this process will be released to the environment.
Answer: Decomposition of organic matter
Explanation:
Decomposition is a biological process that involve the breakdown of complex organic matter into smaller molecules to release minerals forms of nutrients and carbon dioxide. Bacteria help in decomposition by feeding on them and release nutrients. There are two forms of decomposition, the aerobic I.e it occur in the presence of oxygen by the activities of aerobic bacteria or anaerobic decomposition which occur in the absence of oxygen by the activities of anaerobic bacteria.
DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.
DNA cannot be copied; it must be translated to RNA and then back to DNA.
DNA cannot be read by ribosomes; they can only read RNA.
Answer:
DNA is double-stranded and cannot fit through the nuclear membrane; RNA is single-stranded.
